partCount
part counter only lets the count through for a part of the whole range. The last count position can be kept when "sustain" is high, otherwise it goes back to 0 when it reaches the maximum length.
Inlets
int32 count
Outlets
int32 out
int32 range
Parameters
bool32.tgl sustain
int32 range
frac32.u.map offset
frac32.u.map length
Control Rate
int32_t length = ___SMMUL(param_range << 3, param_length << 2);
int32_t offset = ___SMMUL(param_range << 3, param_offset << 2);
int32_t count = (inlet_count + offset -
((inlet_count + offset) / param_range) * param_range);
outlet_out = count > length ? 0 + param_sustain *param_length : count;
